The modern cement plaster covering the dome was meticulously removed, uncovering over 200 holes—remnants of scaffolding from the 20th century repairs—some up to 10 feet deep. These holes were filled with rubble stone and lime mortar to prevent water ingress. The dome's surface was then re-plastered using traditional lime mortar, finished with a 1 mm thick layer of lime punning.

With the deep holes, the internal dome had signs of deterioration with cracks on the surface causing water ingress and vegetation growth. Plaster was restored on the internal dome surface.

Repairs on the blind arches situated below the internal dome were carried out using traditional lime mortar. 20th century cement and white-wash layers were carefully removed to reveal the original appearance. Ornamental details, moulding bands, arch crowns and original lattice screens were repaired by master craftspeople. Traces of original color were also revealed on the ceiling medallion, where found missing, the color was then restored based on the existing evidence. 

20th-century cement concrete on the middle terrace, causing rainwater seepage and structural strain, was replaced with traditional lime concrete in an appropriate slope, ensuring proper drainage. 

The middle level parapet of Hayat Baksh Begum’s tomb comprises thick hand chiselled granite blocks covering a length of 135 m. Over time, the stone joints developed gaps and had vegetation growth within the joints. After removing thick plant roots, all stone blocks were manually reset by skilled stone masons. Seventeen metal waterspouts were installed in existing openings to effectively drain rainwater away from the structure. 

Repairs and restoration works were carried out on the upper portion of the external façade of the mausoleum where broken, damaged, or missing stucco details, merlons, medallions, and floral bands were restored using traditional lime plaster and finished with a coat of lime punning as per the in-situ evidence.

Cement layers were removed from the corner minarets and replaced with lime plaster. Missing and damaged details were restored, and finials were re-installed. Similarly, the damaged portions of the battlements were also repaired.
